IMy iinvention relates .to anew and `useful liquidsprayer.: construction, including an Aair pump, a liquid container, and .means for drawingftheliqu-id .from the liquid container in'. adrip-collecting baille .may be provided at the` discharge Iend ofithe pump in a quick and easymanner, and whereby said' dripcollecting baille may be made durable ,i and im; atthesame timelinexpensive.

Y `Vifith theabove. ends in view, my V inven- -tion consists of. a. manually operable air 4pump :having an elongated,cylindrical body Y .within which a piston isadapted to be re- 35 ciprccated by a piston rod having an external handle. .According to my invention I 'form the discharge end of the pump by a seriesof telescoping members, one forming the. end wall of the cylinder of the air pump, and the :otherforming the .drip-collecting baffle plate.

According to .my invention, the end wall of ".thecylinder ofthe air pump is provided with a comparatively ideep,` cylindrical flangei Which is adapted'to telescope within the .end

' Vdripfcollecting baille is provided with a cylinof the. cylinderofthe .air pump, `while the v.dricalflangeloflesser depthwhich is `adapted totelescope v`within 4the ,cylindrical flange of the end plate. VThe endfof theicylinder of the :air pump, as well as the cylindrical flange portions Aofthe end plate and baille plate, are .all provided withl annular seaming rims, whichywhen the three membersr areassembled, are adapted to berolled over eachother to form a single, integral seam between the three separatezmembers, whereby a single y unitary` construction. is obtair'ijedV of great durability and ylow cost.V

:For the purpose of illustrating 'myinvem ftion, I have `sho'wnin the accompanying i drawing one form thereof which is at present preferred :by me, sinceV the same hasbeen found in practice to givefsatisfactory andi reliable: results, although-it is to `be understood that f the `.various instrumentalities of Iwhich my invention consists Vcan be variously `arranged and organized and that ,myinven- .4 tion isfnojtglimited toithe precise arrangement qandorganization of the-instrumentalities as olierein showmand described.

1and atomizing the same by a .jet of air, where- Ytional view of the front Referringvto `the drawing, in .which #like I tional vView similar to that shown in Ei'gurep illustrating aniodiiiedform ofonstruction. f In carrying out my invention lprovide. a pump cylinder 6, fcrmedofheet metal seamed by a longitudinalseam `(not-shown in -the'- drawing). A, terminal blockj` 7*,lgof wood or, the like, is inserted into the rearlend of thecylinder 6, to form a closuretherefor and to` support .and guidethe piston rod-u8.

.The terminal block 7 Visretained-in :the end ofthe cylinder 6 by aseries vof screws 9 vor any other suitable means.' The pistoni-rod Spasses through an axial openinginythe/terminalblock 7, and carries at itsA outer end a suitable handlelO. Tothe'finnerfendof the piston rcd8, Va cup shapedleather. Wilher 1l` is secured, which together'fwith tliesupporting metalt Washer 12 forms a piston leffectiveV in compressing air in ad.vzmcegof.the Washer 11. The free orflooseyvasher lliizlrrried on the` outer endfofgthe'piston rod,8,AH and thelugs 14 `pressed ,from'thel sides ofthe `r'od 8, serve to Vlimit thestroke of the y piston, by abutting against the outer wall of the terminal block ,7. u

The dischargeend of the cylindrical 'body'` 6 i'slanged outwardly to a Aslight extent, 'as

indicated at l5 1in Figure 4. The terminal wall-in'ember of the cylinder, designated generally by the numeral 16 (Fig. 4) is formed cup-shaped, including the transverse wall 17,7M

with its centralV dischargefopeningoriport 18, and the cylindrical .wall portion 19 ofV suitable length, adapted; to ateleecopel within the'end ofthe cylinder'. A seamingfflange 2O is also formed on the outside or .pre-edge` of the cylindrical wall portion 19, which-is ultimately adapted to overlap the seaining flange on the cylinder 6.

' A baiile member, designated generally by the numeral 21 (Fig. 4) is provided with a generally conical portion 22, having a hori-V ze 21 then is flared outwardly into a. seaming i5 ilange 25, which is adapted to be rolled over the seaming flanges and 15 of the'terminal member 16 and cylinder 6respectively. By

' so' uniting Vthe-assembled parts, as shown particularly in Figure 3, by a single rolled or crimped seam 26, a firm and durable Construction 1s obtained,.with a minimum of vcost and operation. f Corresponding openings 27 and 28 vare pro- Y vided in the cylinder wall 6 and in the cylindrical wall 19 of the terminal member 16, so when the two are assembled in! the mani ner shown particularly in FigureY 3, the two holes will coincide and provide a perforationthrough the ydouble thickness o f metal,

for the reception of the liquid suction tube '29 of the sprayer. `The holes 27 and 28 are slightly largerA than the liquid suction tube 29, so as tok provide some clearance around the outside of the tube 29, for draining back the drippings into the liquid container 30.

The liquid container 30 (Fig. 3) is provided with a perforation 31, preferably somewhat larger than'the periorations 27 Land 28, forthe reception of the liquid suction tube 29.' The aperture 31 is made somei what larger so that the apertures 27 and 28 .60 l VVinserted through the apertures 27 Aand 28,

may be more readily matched with the aperture 31 during thel assembling operation,

vwithout the exercise of too much care* or without consuming too much time. l

In assembling my novel liquid sprayer "construction, I lirst assemble the terminal member 16 and the baille member 21 vupon the end of the .cylinder 6, by means of the l,seam 26.V During the Yassembling of these parts, care must be merely taken toY match Ythe aperture 28 with the aperture 27 in the lcylinder 6. The apertures require no further attention` during'the entire assembling,

because the member 16 will telescope into the cylinder 6 with suliicient friction to retain the former Ywithin the latter securely during the seaming operation.` t

Thereafter, the liquid suction tube 29-is andsecured against the transverse wall 17 by means of'solder, as at 32, .with the top of the tube disposed at the center of the aperture 18, so that the jet of air emergingrfrom the aperture 18 will draw the liquid through the tube 29, in the usual manner.

Y The pump cylinder 6 is then superimposed upon the container 30, in a manner shown in Figures 2 and 3, with the tube 29 extending through the aperture 31 in the container. Y

construction, and one whichy may be pro--V duced at a minimum cost.

Due to the horizontally disposed elliptical opening 23 in the balile wall 22, a generally horizontal, fan-shaped spray is emitted from thev sprayer, thereby tending to give. the maximum distribution of spray for a given amount of liquid.

Any liquid which coagulates into distinct drops before the stream of air has an opportunity fully to disperse the same, drips on to the baille plate 22 and flows downinto the chamberv 36, formed between said balileplate and the -terminal wall 17, Afrom whence kit drains-back into'the container 30 through the apertures 27 and 28 and the aperture 31. Thus, the liquid'is conserved' toithe maximum extent. i t

In Figure 5 I have shown a: modiiied kconstruction embodying myv invention, wherein the cylinder 6 instead of being aiiixed to the Vbcdy ofthe liquid container 30, is merely affixed to a screw cap or other similar closure member 37, to which in turn, a liquid container 38 may be detachably securedin .the manner shown in the drawing. By this means the same pump may be attached to any one of several containers, and the liquid may be used directly from the container in 4 which itris.

shipped and sold. Thus, it -is merely necessary to unscrew thelusual screw cap of the container and replace it with the screw ,cap portion 37 of the pump 6. Y
